The 1.6t is allready N4, becuse N4 is class for over 2000cc engines, which 1.6t is.

Err, I think you mean to say that N4 is for engines greater than 1600cc and up to 2000cc?

But your right, N4 regulations wont need to change to suit the new 1.6T WRC.

Well.. no. If I remember right, there is a multicipation factor for turbo engines, which is 1.7 or something. So 1.6t is 2720cc as 2.0t is 3400cc. You dont need to have turbo with N4, just over 2000cc with or without turbo.
Or am I totally out there...

Think the m/factor is 1.4 which would make N/A 2,200 cc. Used to be that when Renault had the turbo in F1 with Arnoux etc.

I'm only guessing Grug, I'm sure it's hidden away somewhere on the FIA site.

I'm pretty sure it's 1.7 :)

You're right. 1,4 was more than twenty years a go.

Yes, totally behind the times, it's now 1.7. Sorry Grug, you were indeed correct.
